Google Identity Toolkit add third-party authentication

Question

I'm looking for a way to add social sign-in to our website and I found the Google Identity Toolkit solution.

It looks great and easy to set-up, however I am wondering if there is a way to customize this Toolkit in order to add other third-party authentication provider (like Linkedin or Twitter)

I have found this thread which was talking of adding it to the v3, but apparently there is still nothing available?

I'm in the same path, trying to find how to implement it in my ASP.NET C# webapp — Liron Harel, Jan 19 '16 at 17:31
Finally I decided to go using Pac4J for more flexibility (http://www.pac4j.org/) I'm sorry @IdanShechter, I don't know any equivalent in C#. I hope you'll find something! — Théo camb., Jan 25 '16 at 12:01

You can use the Restapi Identity Toolkit.

verifyAssertion

So you can log in with your account: Google, Facebook, Twitter, Github.

For example login with google will look like this:

POST ...verifyAssertion?key={{server_key}}

with body:

{
  "postBody": "id_token=token_value&providerId=google.com",
  "requestUri": "http://localhost",
  "returnIdpCredential": true,
  "returnSecureToken": true
}

where providerId is a provider type and id_token is a oauth2 token of google account in this case
